' My inventionrelates to a device for wrapping longitudinally wrappinglengths of material, such as bead cores, used in building pneumatic tirecasings, withfabric or other 1naterial andmore particularly to a device0 mounted to apply spring pressed toward the which will apply thewrapping 'a number of times about a length of material.

In the accompanying drawings which illustrate one embodiment of myinvention Figure 1 is a side elevation of the device, the wrapper beingomitted in the interest of clearness,

Figure 2 is a plan View of the structure 7 shown in Figure 1,

Figures 3', 4 and 5 are diagrammatic sections showing the wrappingsteps, substantially at the lines 33, 44: and 5-5 of Figure 2.

instrumentalities. As shown in Figure 1 the bead core 5, drawn from anysuitable source of'supply, is applied to the fabric strip 6 as thelatter passes over a roll 7 from tension rolls 8 and 9, a grooved guideroll 10 press ing the core into adhering contact with the fabric strip.The assembled core and fabric then pass to a preliminary wrapping meanscomprising a grooved wheel 12 and folding blades 14 and 16. As shown inFigures 8 and 2, the core is applied off center of the strip and blade16 applies the short edge of the fabric to the core, while blade 14underlies the longer edge of the fabric and assures the application ofthe strip to the side-of the core in position to be engaged by the firstof the series of wrapping rollers 18. A second guide roller 19 maintainsthe core in contact with a substantial are of the wheel 12..The'wrapping rollers 18, which are preferably grooved are mounted inopposed pairs as is shown in Figure 2 and are supported by frames 20secured to table 2 at 21.

The rolls 18 are carried'in forked menibers 22 adjustably mounted inframes 20 by set screws 23. One roll of each pair is spring 1925. SerialNo. 41,294.

is clearlyshown inFigures 4 and 5. This angular relation o'fthe rollsimparts a turnmg or twlstmg motlon to the core as the latter passesthrough the rolls, thus rolling the core into the wrapper. Figure 4:shows the wrapping about half completed while Figure 5 shows thewrapping nearly completely applied. Fromthe last pair of rolls 18 theWrapped core passes over wheel and around a tension wheel 31 mounted atone end of a lever 32 pivoted to. a bracket 83 secured to table 2. Aweight 34attached to the other end of lever 32 urges wheel 31 againstvwheel 30. The shaft 35 of wheel 30 is connected for rotation to anysuitable source of power, not shown, and. wheel 12 is driven fromshaft35 by means of a sprocket chain 36 passingaround sprockets 37 and38 mounted respectively on shaft 35 and shaft 39 of wheel 12. 1

The operation may be summarized as follows: The core and'fabi'ic stripsare brought together as they enter between rolls 7 and 10, the corepositioned adjacent one edge of the strip. From rolls 7 and 10 theassembly passes to a preliminary. wrapping means vcomprising a groovedwheel 12 and co-operating folding blades 14 and 16 which bring thewrapper into smooth contact with a major portion of the circumference ofthe core as sho'wn in Fig. '3, aguide roll 19 maintaining the assemblyin contact with a substantial are of the roll 12. The assembly thenpasses to the first of the inclined wrapping rolls 18 which roll thecore into the fabric, vas.indicated in Fig.fl, succeeding rolls 18continuing 'therolling action until the core has been completely rolledlongitudinally into the strip 6. v The core in its completely wrappedcondition passes around wheel 30 s r n eaeor am ns5 m i g the andtension Wheel 31. Rolls 12-and 30 being positively driven advance theassembly through the machine, Wheel 31 through Weight 34 applyingsufficient tension to maintain this driving relation. The assemblyhaving been initially threaded or led through the machine the operationproceedsas a continuous operation, the machine being stopped to permitsplicing of new lengths to the ends of core 5 and Wrapper 6 before theends of the exhausted-supply enter rolls 7 and 10.

lVhile I have shown my invention'applied tothe Wrapping of bead cores itWill be understood that my invention is not limited to such use andtheword coreis used in the claims in a generic sense.
